These guys are great mid-level tames. You knock them out like most other creatures and shove food up their face. They make great stone, metal, or flint harvesters but I though about this while taming one today. What If there was a setting that they would harvest any nearby mineral/rock, AND you could chose what they harvest. For example, you go to options, see a setting button that says “ Harvest setting “ and click on it. Once you open that up, you can choose what you want your tame to harvest. Metal, stone, flint etc. it goes around hitting rocks and ONLY collecting stone, like you wanted it to. Have a great day!
